Patent DE-4336466-A1 (DE)
Title: Actuating device with a securing means
Inventor: ALBER PIERRE
IPC: F16D3/205
Filed: 1993-10-26
Abstract: An actuating device, in particular for a motor-vehicle friction clutch, having a drive by means of which a rotary movement can be produced in a preselectable direction of action in order to achieve a predeterminable coupling or decoupling position, and having a crank gear which converts the rotary movement of the drive, via a driven shaft, into an essentially translatory movement of an output member and exhibits a worm gear wheel which is in engagement with the driven shaft of the drive via a helical toothing arrangement, is to be designed such that damage can be prevented even in the event of operating-voltage failure occurring for a brief period during the disengaging operation. This is achieved in that the worm gear wheel is fastened on a shaft which is received in an axially movable manner in a bearing element and, with the introduction of axial forces exceeding a predeterminable amount, can be made to deflect in the axial direction, via the helical toothing arrangement, counter to the action of a securing means with elastic elements.

Title: Electron-beam lithography device with an electron-optics correction system
Inventor: SOHDA YASUNARI
IPC: H01L21/027
Filed: 1994-03-18
Abstract: An electron-beam lithography device which uses a cell-projection method and contains a system for the correction of the electron optics. A shaped electron beam (5) which has been sent through a cell with a complex shape (contour) is pointed at a stage (21) on which a substrate (2) is arranged. A fine hole (3) is formed in the substrate, behind the fine hole there is furthermore arranged an electron detector (4) which receives the electrons which pass the fine hole. The output signals of the electron detector are processed so as to represent the degree of the focus correction and/or the astigmatism correction of the electron optics. When a line-space pattern is used for shaping the electron beam, the output signals of the electron detector have a series of peak-intensity levels which indicate the optimum correction of the electron optics when they are at a maximum. Ideally, there is arranged between the substrate with a fine hole and the electron detector a limiting diaphragm for limiting the detection of the scattered electrons which have not passed the fine hole. <IMAGE>

Abstract: The method involves converting the picture into a digital signal. The signal is processed. It contains typical characteristics to identify the person. Many parts of the signal contain typical characteristics of the person. The signal amplitudes in different, non-neighbouring signal areas are compared. The filtering process involves using signal areas apart from each other. They are ordered in the form of parameters using a learning process. A minimum value of a function, involving the pattern signals and the signal group filtered is calculated. It is repeated for other signal groups during the learning process with the picture of the individual. The results stored in the memory provide recognition patterns.
Patent DE-4438256-A1 (DE)
Title: Flanged bobbin
Inventor: SCHLOTTER ALEXANDER C P
IPC: B65H75/22
Filed: 1994-10-26
Abstract: A flanged bobbin has two flanges (2 and 3) which are each fastened axially to the bobbin shank (1) by means of a bush (4 and 5). The bushes have at their outer end a collar (9) which is fastened to the shank by bearing on the outside of the flanges. At the inner end, the bushes have one or more projections (10) arranged next to one another and extending in the circumferential direction. The shank (1) has, on its inside, corresponding axis-parallel recesses (6) and peripheral grooves (7 and 8) near both ends. The flanges likewise have corresponding recesses. To fasten the flanges by means of the bushes, these are attached to the tube in such a way that the projections (10) are aligned with the recesses (6). The bushes can then be pushed axially into the shank, until the projections are level with the grooves and the collars are located on the outside of the flanges. As a result of the rotation of the bushes, the projections and recesses are no longer in alignment and the flanges are fastened to the shank. The flanges can be released from the shank again by the reverse procedure. <IMAGE>

Patent WO-8603807-A1 (WO)
Inventor: GRUENWALD WERNER
IPC: H01T7/00
Filed: 1985-12-05
Abstract: Le procédé concerne la fabrication d'électrodes à haute tension, contenant du calcium et du silicium, pour le système d'allumage d'un moteur à combustion interne. Pour augmenter la résistance et par là aussi pour prolonger la durée de vie de ces électrodes, celles-ci contiennent, outre le calcium et le silicium, du fer ainsi que, cas échéant, de faibles quantités de tungstène et de molybdène. Ceci a pour effet d'abaisser la tension d'allumage et d'améliorer les caractéristiques du déparasitage. Un avantage important du matériau constituant les électrodes comprenant du fer et du siliciure de calcium, est qu'il ne permet que difficilement la formation de ponts de contact lorsque l'électrode présente une zone de contact qui se compose d'un métal ductile, notamment de fer. Pour la fabrication des électrodes, il est nécessaire que le mélange de poudre de fer et de silicide de calcium soit granulé, d'une part pour en faciliter l'usinage, mais surtout pour éviter la séparation des constituants.
